I am not a topologist, but I can try…
A space (shape) is contractible if you can “contract” (shrink) it to a point without cutting, pinching or punching through holes. For example, a mattress is contractible, since you can shrink it to the center - just shrink along each line to the center. Meanwhile, a doughnut, a circle or a hollow sphere are not contractible, you can never remove the inner “hole” to shrink to a point without cutting.
In general, any dimensional sphere is not contractible… Until it isn’t - infinite dimensional sphere is . Somehow, it loses the “hollow space” inside.

I guess it was misjudgement saying Trump is smart for doing so, when he could just… not start a war and tried other disruptions instead.
I did want to ask if war is going to end and Trump is getting away with it, but decided to go one step too far (maybe for virality? Dumb me again)
So much for me believing there is truly no stupid questions.

Is this opinion piece implying that quantum computing researchers should stop researching because current quantum computers are currently less than proof of concept? Is technology supposed to be fully mature from the beginning?

I am realizing I were only good at tests… So sad that I am one of the dumbest and just managed to fool some people with grades. But that does not help with real life.

Please please please do not bork this one, I don’t want to abandon another game I love. Hopefully it’s not like KSP 2 or Cities Skylines 2

Security by obscurity does not work, because people are only so creative up to a point. Hence, there are only handful of configurations for the attacker to try out.
This contrasts to e.g. 128-bit secure encryption, which involves trying 2^128 times to break it - which is a number with whopping 38 zeros. It takes 10^22 years to break it with trying at 1GHz rate. It is simply incomparable, and adding a few bits of security by obscure combination is simply not worth it.
Yet, so many people and organizations seem to prefer obscurity to actual security.

It still has two holes compared to a ball, and that is our usual frame of reference.

Ah, that would be a loophole.

Dunno why people think this is the worst solution. Don’t many of those people love to pee in streets, rather than bother to find toilets? This sounds like an excellent deterrent, and that it works shows that people needed comparative incentive to use the toilet.

Yeah, not everything is about the homeless. Are there actually many homeless in Munich, compared to rude tourists?

Ah, joy of commutative algebra.
Wait until you get to noncommutative algebra… shudders. No one who mastered that monster of a subject is sane in any measure.

I mean, it would help you understand what a ring is, if you know monoids. It clearly helps. Right? …right?
I mean, that one is a tame example compared to e.g. ncatlab.org/nlab/show/homological+algebra

I watch expert twitch streamers’ play to learn the plays, card picking and risk control. It helps greatly in playing A20H and start your first win streaks. You can also see them making mistakes, which gives a point of reference
